Wheat is about to enter the rejuvenation period, many farmers friends are ready to pour back to Qingshui, and some farmers are rushing to pour wheat in the ditch. The author gives everyone a wake-up call: wheat should be green, and fertilizer should be cautious.
The main factor affecting wheat growth during the regreening period is not the water but the temperature. Although the temperature gradually rises after the spring, the nighttime temperature is still low, and the temperature suitable for wheat growth has not yet reached. As long as the sensation is sufficient, raising the ground temperature by cultivating the loose soil is the focus of the field management of wheat during the greening period. The temperature of the ground is closely related to the soil water content. The spring climate in our province is characterized by windy and drier rains, frequent cold springs, and early spring watering is likely to cause large field cooling, which is very unfavorable for the growth of wheat after greening. It is caused by freezing damage, so don't blindly pour back into Qingshui. The return of green fertilizer and water should be scientifically mastered. Fertilizer water will cause excessive ineffective splitting in spring, and the population will be too large. One will cause nutrient waste, and the other will lay a hidden danger for late lodging and pest damage.
First, pour the water turning green time should be given to those who rob moisture in planting before winter watering is not yet frozen water, poor soil preparation quality, poor field moisture loss and severe crop wheat ontogenesis, the small group of serious drought in wheat fields should be based on soil moisture The green water is poured back in time, and the time for pouring back to the green water can only be carried out when the daily average temperature reaches 3 °C or higher. Generally, in the wheat field, as long as the lyrics are allowed to be delayed or not poured back to the Qingshui, the spring water will be postponed until the body is lifted or jointed. For the wheat fields with small population growth potential or weak winter and long spring, the urea can be applied with 10 kg of urea in combination with watering, and the water is treated in time when the wheat field is suitable.
Second, pouring back to Qingshui to strictly control the amount of watering due to early spring and night temperature changes and the frequent alternating cold and warm water flow, watering should be poured with small water, not suitable for flooding, to prevent the occurrence of cold current temperature and ground temperature too low to wheat Causes freezing damage.
Third, pouring green water according to the seedlings on the wheat field suitable for sowing in winter, due to insufficient soil fertility, resulting in less tiller, insufficient number of spikes (about 500,000 per mu of total stems before winter) can be poured back to Qingshui, and combined with pouring Water 7.5-10 kg per mu, add 5-7.5 kg of potassium sulphate or potassium chloride to promote the early spring tiller production, try to get more spikes as much as possible, lay a good foundation for high yield; late sowing wheat and total number of stems 70-900,000 strong seedlings or more than 900,000 more than the seedlings and fertilizers are generally not poured back to Qingshui, with cultivating loose soil and maintaining warming, and springing the tillers to the minimum; winter long wheat fields due to winter The amount of pre-growth is large and consumes a lot of fertilizer and water. Before winter, the frozen water is not watered. The field is very bad. In the early spring, it is easy to cause cold seedlings due to cold spring. It should also pay attention to timely returning to Qingshui.
In short, the return of Qingshui to the ground, due to the appropriate conditions, should not be blind, so as not to cause unnecessary losses.
